The invention relates to a hoisting device, and more especially todevice adapted for lifting or hoisting highway signs.

A primary object of the invention is the provision of means whereby ahighway or other sign can be readily and easily lifted into position forvisibility, without undue strain or physical labor.

Another object of the invention is the provision of a device of thischaracter which can be fitted to an upright or post, within easy reachof the operator when standing upon the ground or a foundation, so thatthe sign or the like can be raised or lifted to the desired elevatedPosition with ease and dispatch.

A further object of the invention is the provision of a device of thischaracter, which is extremely simple in construction, thoroughlyreliable and eificient in operation, strong, durable, readily and easilyoperated, conveniently applied to and removed from an upright or postand inexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts, as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which show the preferred and modified forms of construction ofthe invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a front elevation of the device constructed in accordancewith the invention, showing a sign in a lowered position to be hoistedthereby.

Figure 2 is a side elevation of the structure shown in Figure 1, showingby full lines the sign in position to be raised or hoisted, while bydotted lines is shown a sign to be lifted by a change in the position ofparts of the structure.

Figure 3 is a fragmentary side elevation on an enlarged scale of thedevice, both in the preferred and modified positions as illustrated inFigures 1 and 2.

Figure 4 is a fragmentary elevation showing the block and pulleyarrangement.

Figure 5 is a top :plan view of the clamping yoke carrying the windingand unwinding winch or roller of the device.

Figure 6 is a fragmentary side elevation thereof.

Figure '7 is an elevation of the capping pulley for the post or upright.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

1 Claim. (01. 254 14 5) Referring to the drawings in detail,particularly Figures 1, 2 and 3, there is illustrated a pair of spaceduprights or posts I ILwhich are perpendicularly anchored within afoundation or the ground at the selected location of a highway sign II,the sign in this instance being of elongated or rectangular shape. Apair of hanger bails I2, provided with loop-like attaching ends I3 arepositioned about the sign II. Hanger hooks I4 are detachably engagedwith bails I2. The hooks I4 are loosely connected to lifting or hoistingcables I5 which are trained over the pulleys I6 of a block and tackle,each having its tackle I'I detachably engaged with a suspension eye I8fixed to the outer end of a horizontally arranged outwardly projectinghanger arm I9. The arm I9 in each instance, is made fast to the head ofan upstanding pulley frame 20 which has its base 2| secured to a cappingpiece 22 adapted to be telescoped over the upper end of the upright orpost ID. The capping :piece 22 is made fast in capping position by a tiebolt 23 passed transversely through the upper end of the upright or postID, as best seen in Figure 3.

The cable I5 is adapted to be wound on and unwound from a winch orroller 24, having an axle 25 journaled in the side arms 26 of a clampingyoke 21 carrying clamping heads 28 and 29, the heads being fixed withinthe yoke 21 at diametrically opposite points. Head 29 is fitted on anadjusting stem 30 adjustably threaded in the arm 25 next thereto and hasat its outer end a turning Wheel 3|. The heads 28 and 29 fasten the yoke21 in a horizontal position upon the upright or post I!) as best seen inFigures 5 and 6. The axle 25 has detachably fitted thereon a crankhandle 32. Yoke 27 can be shifted to one side and the other of theupright or post I0 for a selected use of the hoisting device, breleasing head 29 through rotation of wheel 3|.

Pulley frame 20 has journaled therein a pulley 33 which may have trainedthereover a hoisting cable 34 which can be substituted for the cable forthe lifting or hoisting of the sign II as is clearly shown by dottedlines in Figure 2 of the drawings.

This cable 34 is adapted to be wound on or un Wound from the winch orroller 24 and can be attached to the sign similarly to the attachment ofthe cable I5 or otherwise. The roller or winch 2 4 can be held braked inany suitable manner.

Either of the cables l5 or 34 is selectively usable for the hoistingpurpose in lifting the sign II or for the lowering thereof as the casemay require,

and. the frame 20 may be suitably positioned as above described for theuse of either cable.

From the foregoing it will now be seen that there is herein provided adevice accomplishing all the objects of this invention, and others,including many advantages of great practical utility and commercialimportance.

As many embodiments may be made of this inventive concept, and as manymodifications may be made in the embodiment herein shownand described itis to be understood that all matter herein is to be interpreted merelyas illustrative and not in a limiting sense.

What is claimed is:

A portable sign hoist comprising a socket adapted to be mounted on theupperend of-asig -nzpost, a pulley frame extending axially .from theupper end of the socket, a pulley mounted in the frame to rotate about ahorizontal axis, an armex-tending outwardly from the upper end of theframe along :an .axis which lies perpendicular to the axis about whichthe pulley rotates, .an, eye depending from .the end of the arm, remoteItem the pulley frame, a pulley detachably suspended from the eye, ayoke adapted to be clamped to the sign post intermediate its upper andlower ends, a winch mounted in the yoke to rotate about a horizontalaxis, a flexible hoist cable coupled at one end to th winch and adaptedto be trained over one or the other of said pulleys, and a sign liftingbail detachably coupled to the end of the cable remote from the winch.
